Aluminum fluoride and 1-4 parts of partial size are less than the magnesium fluoride of 0.074mm, are sufficiently premixed in blender, obtain premix material；
Step 2 is subject to the water of pre-composition material weight 5-8% and the starch of 5-10% into the premix material of step 1 outside, is placed in mixed
Continue to be kneaded 10-20 minutes in mill, the pug after being kneaded；
Pug after mixing is put into mold and carries out molding casting by step 3, after sample conserves 24-48 hours in a mold
Demoulding forms porous ceramics green body；
Step 4, it is dry, the porous ceramics green body after demoulding is 24-48 hours dry under conditions of 110 DEG C；
Porous ceramics green body after drying is warming up in high temperature furnace 1350-1550 DEG C, calcined 2-6 hours, then drop by step 5
Temperature keeps the temperature 2-6 hours to 650-850 DEG C, finally with taking-up after furnace natural cooling to get to magnesium aluminate spinel whisker reinforcement
Alumina hollow ball porous ceramics.
Preferred calcination time is 2-4 hours in the step 5.
Compared with prior art, the beneficial effects of the present invention are: 1) magnesium aluminate spinel whisker reinforcement prepared by the present invention
Alumina hollow ball ceramics, by resourceful Al2O3, MgO matter raw material preparation, it is low in cost；2) magnesium aluminate spinel whisker has
Excellent high temperature resistant, corrosion-resistant, superior thermal shock resistance and mechanical property, being introduced into porous ceramic film material can be improved material
Toughness, increase impact strength, be conducive to improve ceramic material service life.3) whisker can play the work of toughening to brick body
With the excessive toughening effect of the draw ratio of whisker is poor, and draw ratio is too small, and product can't be whisker, referred to as crystal grain, major diameter
Than for reinforcing effect between 10 ~ 70 it is best.
